"During 2015, El Salvador, a country with a population of 6.5 million people, recorded some 6,657 murders. As a result, El Salvador probably posted the world's highest homicide rate, an alarming 104 per 100,000 people, last year. El Salvador has the highest concentration of gang members per capita in Central America; as a result, gangs are responsible for a higher percentage of homicides there than in neighboring Guatemala and Honduras. The current level and type of violence that El Salvador has experienced--including massacres, killings of police and their families, and extrajudicial killings of suspected gang members--rivals the worst periods of the country's civil conflict (1980-1992). […] Escalating violence in El Salvador and the ongoing political polarization in the country have inhibited the success of U.S. and Salvadoran efforts to improve security and bolster growth and investment under the Partnership for Growth (PFG) that began in 2011. U.S. law enforcement and prevention programs funded through the Central America Regional Security Initiative (CARSI) have begun to be co-located through a 'place-based approach' in the same cities that the Salvadoran government has prioritized (see CRS Report R41731, Central America Regional Security Initiative: Background and Policy Issues for Congress). Those programs could potentially be scaled up using funds provided in the Consolidated Appropriations Act, 2016 (P.L. 114-113)."
